[問題] 普化-固體,四面體洞?八面體洞?
寫題目寫到下面這一題
A mineral crystallizes in a cubic closest packed array of sulfur ions
with aluminum ions in one-half of the octahedral holes and zinc
ions in one-eighth of the tetrahedral holes. What is the formula of
this mineral?
Ans: Al2ZnS4
我看不太懂他上面寫四面體洞、八面體洞和cubic closest packed的關係耶
是每一種堆積(面心、體心、立方)會有配不同的四面體or八面體洞嗎?
而且鋁離子佔八面體洞的1/8也看不太懂是什麼意思
煩請板上前輩解說一下 謝謝^^"
